Frozen Stiff! (The Secret World Of Alex Mack #12)

Alex morphs, freezes, and is nearly caught by a self-important scientist.

Long Synopsis:

When Alex took a job at the local grocery store to earn a little extra money, she thought it would be a piece of cake! But it turns out to be a cake (the one that Alex's mom has ordered as a surprise for George) that gets her into trouble. Now she's stuck-frozen like a popsicle-after morphing in the store's freezer to retrieve it. Worse, she's right next to the blocks of ice being stored there for a Paradise Valley Chemical Plant experiment. And the ice is about to be picked up by the plant!
Alex needs help-and fast. Can Annie and Ray find her in time and thaw her out? Or will Alex end up on ice for good?
